Researchers Make Progress Toward High-Performing Water Desalination Membranes

http://www.sci-news.com/othersciences/materials/high-performing-water-desalination-membranes-09209.html

Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.

Damage from whopper hurricanes rising for many reasons

 ...America and the world are getting more frequent and bigger multibillion dollar tropical catastrophes like Hurricane Laura, which is menacing the U.S. Gulf Coast, because of a combination of increased coastal development, natural climate cycles, reductions in air pollution and man-made climate change, experts say.

First Methane Leak Found on Antarctic Sea Floor, Confirming Researchers' Fears

Scientists have, for the first time, discovered an active leak of methane gas from the sea floor in Antarctica. It is a process that's likely to accelerate the process of global heating.

cnn.com - by  Ivana Kottasová - January 13, 2020

The world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second, scientists have said.

A new study released on Monday showed that 2019 was yet another year of record-setting ocean warming, with water temperatures reaching the highest temperature ever recorded.

An international team of 14 scientists examined data going back to the 1950s, looking at temperatures from the ocean surface to 2,000 meters deep. The study, which was published in the journal Advances in Atmospheric Sciences, also showed that the oceans are warming at an increasing speed.

Climate Change: UN Panel Signals Red Alert on 'Blue Planet'

CLICK HERE - IPCC - SPECIAL REPORT ON THE OCEAN AND CRYOSPHERE IN A CHANGING CLIMATE - Summary for Policymakers

bbc.com - by Matt McGrath - September 25, 2019

According to a UN panel of scientists, waters are rising, the ice is melting, and species are moving habitat due to human activities.

And the loss of permanently frozen lands threatens to unleash even more carbon, hastening the decline.

There is some guarded hope that the worst impacts can be avoided, with deep and immediate cuts to carbon emissions.
